Kansui Suminagashi Single-Bevel knives are handmade and feature a Jigane, which is made by repeatedly folding together two layers of different types of carbon steels. This unique process creates a Jigane with 16 exceedingly thin, alternating layers, called Damascus. This is then forge-welded to a layer of high carbon steel (blue paper #2) and tempered to Rockwell c63º. This process imparts a visual tension to the blade and a brilliant sharpness to the cutting edge. Because blue steel is a carbon steel, these knives must be dried after use to prevent rust or tarnish.

Traditional Japanese chef's knives differ from European-styled knives in that they are sharpened with a bevel on only one side. The opposite side is slightly hollowed. Because of this, these knives can generally be honed to a sharper edge than can double bevel knives.

The "Wa" style handle is octagonal in shape and is formed from makassar ebony with a buffalo horn ferrule. Each blade comes razor sharp. Designed for right-handed use.
